摘　　要：制4组各分为3层生物滤池反应柱,分别填装火山岩、陶瓷鲍尔环、多面空心塑料球和聚丙烯整装滤料,研究了每组反应柱中各层滤料以及每层中各段滤料在处理校园生活污水时各自的去污特性。结果表明,火山岩滤料在降低污水中各污染物指标的性能最强,其次是陶瓷鲍尔环和多面空心塑料球,聚丙烯整装滤料对所有污染物指标的去除效果都最差;就单层滤料而言,其对水中COD、氨氮和TP的去除主要集中在前60 cm段,对TN的去除主要集中在后20 cm段。The homemade four groups of reaction column which were divided into 3 layers of biofilter,were filled volcanic rock,ceramic pall ring,multifaceted hollow plastic ball and polypropylene filter.The each layer filter material of the reaction column was studied,and decontamination characteristics of every layer in the treatment of the campus life sewage was carried out.The results showed that the volcanic rocks had the strongest performance in reducing each pollutant index of sewage,which followed by ceramic pall ring and polyhedral hollow plastic ball,polypropylene package filter material had the worst performance in reducing each pollutant index of sewage;For single filter material,the COD,ammonia nitrogen and TP removal were mainly concentrated in the former sixty cm section,for TN removal was mainly concentrated in the twenty cm section.
